Gumroad vs Sellix

Gumroad is a platform for selling digital products and services such as books, memberships, and courses. Creators can customize a storefront, connect a custom domain, or place payment and follow widgets on an existing site; adding those widgets requires the ability to edit its HTML. Payment options include one-time, recurring, fixed-length, and pay-what-you-want charges in different currencies. Memberships can provide a content library with billing periods including monthly, quarterly, biannually, and yearly. Digital product support includes PDF, ePub, and Mobi versions, plus generated software license keys and lightweight DRM. Creators can import email lists, export follower and customer details, send broadcasts, and create automated workflows. Sales analytics and tracking support Google Analytics, Meta Pixel, and TikTok Pixel. Gumroad also provides an API and buyer apps for Android and iOS. Payout methods vary by country; direct deposit or PayPal may be available. The maker says it handles worldwide sales-tax collection and remittance as merchant of record. Direct sales cost 10% + $0.50 per transaction; Discover sales to new customers cost 30% per transaction.

Sellix is a commerce platform for digital and physical goods, offering public shops, hosted checkout, and a management dashboard. Checkout is crypto-only: buyers select supported assets while displayed fiat prices are converted during payment, and cards are unavailable. Products can include license keys, file downloads, accounts, Discord roles and invites, physical goods, subscriptions, and custom payloads. Confirmed payments can trigger keys, signed download URLs, webhook payloads, or physical-order status. The REST API and signed webhooks support custom integrations, with BlockPN settlement and Discord delivery documented. API keys use granular permissions, expire within at most 90 days, and can be revoked. Webhooks use HMAC-SHA256 and retry up to six times. The plan costs nothing with no subscription, take-rate, or expiry. Sellix supports unlimited shops, products, orders, and customers, plus custom domains, teams, roles, and 2FA.
